Su Yu stayed at his elder brother's place for a day, then went with his niece to Clear Water No.5 Grotto Heaven, which is only five thousand kilometers from Yangliu Town, to see his parents.
The so-called Clear Water No.5 refers to the fifth Grotto Heaven in the Clear Water River area, and there are six such Grotto Heavens in total.
The Grotto Heaven covers an area of 2.48 million square kilometers, housing billions of mortals, as well as a few retired cultivators.
Usually, it's the low-level cultivators, since Loose Immortals who've crossed the heavenly tribulation generally don't retire, they work until their lifespan is nearly over.
Moreover, even if Loose Immortals retire, they won't hide in the Grotto Heaven; no matter how old they are, they still hold certain power and can stay within the Earth Immortal Realm.
